Interactive comment on “ Effects of Micro-Arrangement of Solid Particles on PCE Migration and Its Remediation in Porous Media ” by Ming

Comments accepted . We appreciate Dr. Pacheco’s conscientious and positive recommendation. We have made great efforts to implement the “minor revision” to improve our manuscript as suggested. This research aims at characterizing the important effect of micro-structure on macroscopic scale characteristics of aquifer and inner contaminant migration and remediation. To achieve the aim of this research, the first step is to explore the issue of theory and simulation. Fractal models of regular triangle arrangement (RTA) and square pitch arrangement (SPA) at microscale are developed to evaluate contaminant movement and associated contamination reme-
